FAQ
How do I confirm an intake leak?
A smoke test is the fastest way to find vacuum leaks. Coolant-type intake leaks may need a pressure test and inspection.
Should I resurface the intake?
Aluminum intakes can warp. Check them with a straightedge and follow the manufacturer's guidance.
What else should be done while it's apart?
Rear-bank spark plugs and coils, vacuum lines, and the PCV system are common add-ons.
